很多人表示对于很多工程中的MATCH_PARENT出现在layout中感到不明白,过去只有FILL_PARENT和WRAP_CONTENT那么 match_parent到底是什么类型呢? 其实从Android 2.2开始FILL_PARENT改名为MATCH_PARENT ,从API Level为8开始我们可以直接用MATCH_PARENT来代替FILL_PARENT,最后Android123提醒大家,他们的定义本质是一样均为 -1,只是换了个别名,可能为了更准确些,比如最终在SDK中的定义为:
fill_parent -1 The view should be as big as its parent (minus padding). This constant is deprecated starting from API Level 8 and is replaced by match_parent.
match_parent -1 The view should be as big as its parent (minus padding). Introduced in API Level 8.
wrap_content -2 The view should be only big enough to enclose its content (plus padding).
MATCH_PARENT和FILL_PARENT之间的区别?
